摘要：
A device (1) for extracting an ingredient in a cartridge (9) by supplying an extraction liquid such as heated water into such cartridge, comprises: upstream and downstream cartridge enclosing parts (7, 8) relatively movable between an open position for inserting and/or removing such cartridge and a closed position for forming an extraction chamber (11) enclosing such cartridge during extraction； and a cartridge removal arrangement (36, 37) for assisting removal of such cartridge when the enclosing parts (7, 8) are brought from the closed to the open position. The upstream part (7) bears an upstream piercing arrangement (34) for opening an upstream portion of such cartridge. The downstream part (8) bears a downstream piercing arrangement (30), such as a piercing member, for opening a downstream portion of such cartridge. The cartridge removal arrangement comprises an upstream pusher (36) for pushing such cartridge away from the upstream piercing arrangement (34) and a downstream pusher (37) for pushing such cartridge away from the downstream piercing arrangement (30).
